This looks like something that VR could benefit from. I've always thought of having shooting like this in first person shooters. Your head is not tied to the direction of the gun. It would require having an 3rd analog stick on the controller. with VR headsets. Your head functions as the camera control. But the thing is that when you rotate your head, your body doesnt rotate either. Alot of thought and design will be required for VR first person shooters.
